1 Claim.

This invention relates to an improved window sash governor and has special reference to a device for holding sliding windows in diiferent elevated positions without the use of sash weights and the like.

An object of the present invention is to provide a device of the character describedwith a resiliently held roller that is adapted to be mounted into a window frame and resiliently pressed against the window sash, whereby the window will be automatically held in different elevated positions and will be prevented from rattling and can be opened in an easy manner.

Another object of the invention is to carry the roller on an axle and to support the axle on an especially formed bow shaped spring that serves to resiliently force the wheel against the window sash.

Another object of the invention is to provide a plurality of holes around the periphery of the roller and to also provide a. spring controlled arm having a. projection thereon and to arrange said arm against said roller, the projection being adapted to fit into said holes and retard the revolvable movement of the roller, the spring also serving to push the roller against the window sash.

Another object of the invention is to mount the roller and other elements into a simple sheet metal case that can be easily positioned into any conventional window frame by merely cutting an opening therein and which will require no special construction on either the frame or the sash.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. l i a side elevational view of the device;

Fig. 2 is a front elevational view of the device;

Fig. 3 is a rearelevational view;

Fig. 4 is a central vertical longitudinal sectional View taken on line 4-4 of Fig. 2 looking in direction of the arrows;

Fig. 5 is a central vertical transverse view of the roller assembly.

Fig. 6 is a front elevation, partly in broken section, of a window and window frame and shows the invention positioned into the sides of the frame and against the window sash;

Fig. 7 is a side elevational view of a bowshaped spring used in the invention;

Fig. 8 is an enlarged end sectional view of the axle taken on line 8 8 of Fig. 5; and I Fig. 9 is a central vertical longitudinal sectional view of a modified form of the invention.

Referring in detail to the drawing and the different parts thereof, the numeral l0 designates rectangular open case preferably made of sheet metal and formed with vertical lips H and I2 on the front end portion thereof and a pair of slots I 4 and I5 through the sides as shown in Figs. 1 and 2. The loose ends of the case are over-lapped as shown at [6 and IT and the front and rear ends of. the case are left open as shown at 18 and IS.

The numeral 2!) designates the roller per se and the numeral 2! a bushing that is fixed therein. The axle assembly consists of the axle 22, a pair of washers 23 and 24 and a bushing 25, the washers and bushing having an excessively tight fit on the axle forming a complete unit. A plurality of balls 26 are provided in the space 2'! between the bushings 2i and 25, thus forming a ball bearing. Said balls are positioned in said space before one of the washers is fixed to the axle. A plurality of holes 28 are provided around the periphery of the roller, said holes being tapered on one side as at 29. Upper and lower slots 30 and 3|, respectively, are transversely provided across the end portions of the axle as shown in Figs. 5 and 8.

Means for resiliently holding the axle within the case is shown as comprising a pair of bow shaped springs 32 and 33 each of which is formed inwardly as shown at 34 in Fig. '7, Said inward 1y bent portions being capable of clamping the axle in the slotted portions 30 and BI thereof. The bow shaped springs fit tightly against the top and bottom walls of the case and the ends of said springs may be bent over asshown at 35 and 36, in Fig. '7, and fixed into said walls. The rollers are thus resiliently held in a manner that will produce a spring pressure against the window sash.

An arm 31, preferably shaped as shown in Fig. 3 and having a bullet shaped projection 39 -formed therein as shown in Fig. 4 is hingedly secured onto a shaft 49 that is mounted into the lower rear portion of the case and extends through the sides thereof as shown in Figs. 3 and 4. A pair of yoke type springs 4| and 42 serve to resiliently hold the arm 31 against the roller, the projection 39 of said arm catching into the various holes 28 provided around the periphery of the roller. The said arm thus acts as a brake and also as a means for producing 'the vertical ends of the window sash 50.

additional spring pressure on the roller to force the same against the window sash. It will be noted that the holes 28 are tapered on one side as shown at 29 but are straight on the opposite side. This construction is provided to reduce friction when the window is moved upward to facilitate the opening of the window, the projection 39 slipping out of the holes easily when the roller is turned in the direction of the arrow 43, but holds more firmly when the roller is turned in the opposite direction, thus firmly holding the window in its upward position. Holes 44 and 45 are provided in the lips H and I2, respectively, of the case enabling the same to be substantially secured to the window frame by suitable nails or screws 38.

Fig. 9 illustrates a modified form of the invention. In this view the arm 31 and springs 4| and 42 are eliminated. The roller 46 is made of a resilient or flexible material, such as rubber or leather and is reinforced by a metal bushing 41. The construction of the case, bow shaped spring and axle are the same as that previously described. 1

Fig. 6 illustrates how the invention is mounted into the vertical sides 48 and 49 of a window frame and shows how the roller is applied against The device can easily be mounted in conventional window frames and no change of any kind is required in the window sash.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departin from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

A window sash governor comprising a casing adapted to be mounted into the vertical sides of a window frame, a pair of vertically curved spring members mounted within the casing and positioned at the sides thereof and supported on the top and bottom walls of said casing, an axl supported on the central portions of said spring members, said axle extending through openings provided in the sides of the casing, a roller revolubly mounted on said axle, ball bearing support between said roller and axle, a series of holes provided around the periphery of the roller, a resiliently controlled arm hingedly secured to the casing and positioned against the periphery of the roller, 3, projection on said arm capable of extending into the holes around the periphery of the roller, one side of said holes being tapered to facilitate for free revoluble movement of the roller in one direction, and means whereby the resiliently controlled arm produces a resilient pressure against the roller to force the roller against the window sash, said mean comprisin a pair of yoke type springs having their free ends in contact with said hinged arm.
